Title: Doorbell Ringer location
Post by: JimNCheryl Domenoe on October 22, 2014, 11:46:49 PM
Does anyone know where the door bell ringer (speaker, bell or whatever sound making device it has) is located in my 2000 Beaver Marquis?  The door bell doesn't work and I'm trying to troubleshoot.

Thanks in advance.

I took the button apart and repaired/ remade the plunger part and now it works fine !!

Where is the ringer, though?

In my 1999 it faces the front on the coach on the front of the passenger a/c controls box.  It's black with a grill about the size of a half dollar.  I found a replacement at radio shack.

Ok, thanks. I wondered if that might be it.

OK, I took the armrest off and discovered that the wires were disconnected.  The leads from the bell were too short to reconnect so I went to Radio Shack for a new one. I also found that a resistor was hooked into the power line.  Not sure why but I suspect it is for the lighted button. The button light wasn't functioning anyway, so I removed the resistor and the bell worked perfectly.  

Thanks to all who provided input on this.

Jim,

There is a bulb in the button you can replace.

Thanks. I'm wondering if the lack of a resistor will damage the light bulb.  Don't know for sure what the resistor is for if not that.

That I am not sure about.

They are probably using the resister to voltage drop as current passes through it. It could be for the bulb to adjust brightness or for the whole unit. The goal may have been to reduce the heat from the bulb so it does not melt the plastic. Probably there for a reason. If it runs a month and no ill affects then you are probably good to go.

Jim,
The component in question is a capacitor. It is between the red and black (12v & gnd) running to the ringer. The blue wire goes to thee door bell switch. See pic. There are no external resistors in the enclosure. (I was doing some maint. on the AC fan circuit so snapped the pic while I was in there).

Thanks Steve.  I hooked it up without the capacitor and it works.  What is the purpose of the capacitor?

I suspect it is either to reduce voltage spikes when button is pushed or to lengthen duration of "chime".

It must be spike protection for the unit or to stop a spike that comes from the unit. It would have no affect on the duration of chime given this is the B+ and ground feeding the circuitry. That is my best guess....

I don't have a Marquis and am not familiar with the doorbell setup, but found the following, if it offers any insight:

Joel, great link.  Any idea what year(s) coaches were affected?
